JellyTunes - Desktop app to sync your Jellyfin music to USB drives/SD cards

[EdgarQuasarZ]

Hey, I made a thing that might be useful here.

  JellyTunes is a desktop app that connects to your Jellyfin server and lets you sync music to USB drives, SD cards, or any local folder. Basically the iTunes "sync to device" experience but for your self-hosted library.

  - Browse artists, albums, playlists from your Jellyfin server
  - Selective sync — pick exactly what goes on the device
  - FLAC → MP3 conversion at 128k/192k/320k for saving space
  - Smart skip — only grabs new or changed tracks on subsequent syncs
  - Per-device sync history, cancel mid-sync, zero telemetry

  Platforms: macOS (arm64 + x64), Windows, Linux (AppImage + deb)
  Download: https://github.com/orainlabs/jellytunes/releases

  Built for personal use (USB drive for the car) and figured it was worth releasing. Happy to hear what's broken or what features would make it worth using for your setup.

Quick update — 0.4.0 is out today.

The main addition is lyrics sync. JellyTunes can now download .lrc sidecar files or embed lyrics directly into the track. Works with Jellyfin 10.9+ (JSON format) and older servers (plain .lrc). Switch modes
and orphaned files are cleaned up automatically.

Also new in this release:
- Cover art mode per device — choose between embedded cover art or a companion cover.jpg. The setting is remembered between sessions.
- Redesigned sync preview — three-column layout showing new / will update / will remove per category, with combined duration and estimated size before you confirm anything.
- Select All on large libraries — pagination is now handled correctly, regardless of library size.

A few reliability fixes too: disk-full hangs during large syncs, stale cover files after mode switches, false "out of sync" detections, storage bar showing inaccurate estimates.

macOS (ARM + Intel), Windows, Linux (AppImage + .deb) — all up on the releases page.
